Abstract
BACKGROUND/AIM To present MRI features of neck lymph nodes in benign and malignant conditions in the pediatric population. MATERIALS AND METHODS MRIs of the neck of 51 patients 1 to 18 years old (40 boys, 11 girls [10.08±4.73]) with lymph node biopsy were retrospectively analyzed. Those were grouped as benign including reactive (27 [52.9%]) and lymphadenitis (11 [21.6%]), and malignant (13 [25.5%]). The groups were evaluated multiparametrically in terms of quantitative and qualitative variables. RESULTS The long axis, short axis, area, and apparent diffusion coefficient (ADC) values of the largest lymph node were 21 (17 to 24) mm, 14 (12 to 18) mm, 228.60 (144.79 to 351.82) mm 2 , 2531 (2457 to 2714) mm 2 /s for reactive, 24 (19 to 27) mm, 15 (11 to 20) mm, 271.80 (231.43 to 412.20) mm 2 , 2534 (2425 to 2594) mm 2 /s for lymphadenitis, 27 (23.50 to 31.50) mm, 20 (15 to 22) mm, 377.08 (260.47 to 530.94) mm 2 , 2337 (2254 to 2466) mm 2 /s for malignant, respectively. Statistical analysis of our data suggests that the following parameters are associated with a higher likelihood of malignancy: long axis >22 mm, short axis >16 mm, area >319 cm 2 , ADC value <2367 mm 2 /s, and supraclavicular location. Perinodal and nodal heterogeneity, posterior cervical triangle location are common in lymphadenitis ( P <0.001). Reactive lymph nodes are distributed symmetrically in both neck halves ( P <0.001). CONCLUSION In the MRI-based approach to lymph nodes, not only long axis, short axis, surface area, and ADC, but also location, distribution, perinodal, and nodal heterogeneity should be used.

Abstract
We present the case of a previously healthy 13-year-old boy who was admitted to the emergency department with acute flaccid paralysis. Magnetic resonance imaging revealed radiological evidence of longitudinally extensive transverse myelitis. Additionally, homogeneous T2 signal increase was observed in the pons and medulla oblongata, initially indicating brainstem encephalitis. Subsequent evaluations confirmed a coexistence of diffuse midline glioma (DMG) in the brain stem alongside acute transverse myelitis (ATM). Children with ATM generally have a more favorable prognosis than adults. However, despite the implementation of advanced treatment methods, the patient's quadriplegia did not improve and resulted in spinal cord sequela atrophy. DMG exhibits an aggressive growth pattern and lacks a known curative treatment. This case represents an exceedingly rare synchronous occurrence of aggressive conditions, underscoring the importance of raising awareness among physicians. Furthermore, we aim to discuss the radiologic differential diagnosis, as this is the first documented instance in the literature.

Abstract
OBJECTIVES Central precocious puberty (CPP) is one of the common reasons for referral to pediatric endocrinology. Magnetic resonance imaging (MRI) is used to rule out intracranial pathologies. However, there is insufficient information in the literature about bone marrow abnormalities on MRI in CPP cases. The aim of this study was to evaluate the apparent diffusion coefficient (ADC) values obtained from bone marrow diffusion weight images (DWI) of cranial bone structures and the status of sphenooccipital synchondrosis (SOS) in CPP. METHODS MRI data from 6-to 9-year-old girls with CPP and a healthy control group were evaluated. Anthropometric data, FSH, LH, and oestradiol tests were recorded, and the relationship between SOS status, DWI-ADC values of the clivus, parietal bone, and occipital protuberance were compared. RESULTS The study included 146 girls, 79 CPP, and 67 healthy aged 6-9 years (median: 8 (2)). The diagnosis age was 8.30 ± 0.8 years. The ADC values were significantly lower on CPP than normal controls (p=<0.05). In the CPP group, pattern 1 was found at 2 % (n=2), pattern 2 at 3.5 % (n=3), and pattern 3 at 3.5 % (n=3) in clivus sphenooccipital synchondrosis. There was no correlation between the mean parietal, occipital, and clivus ADC values and any variable (p>0.05). CONCLUSIONS DWI-MRI ADC analysis can be used as a quantitative radiological marker for early detection of CPP, even before changes in sphenooccipital synchondrosis.

Abstract
OBJECTIVE In vitro fertilization failure (IVF) is high in women with poor ovarian response or non-responder. For this reason, the addition of adjuvant treatments to IVF protocols has come to the fore. We assessed to investigate the effects of adjuvant GH therapy initiated in the mid-luteal phase on IVF success in poor ovarian response or non-responder women. PATIENTS AND METHODS A retrospective study was performed in 93 poor ovarian response or non-responder women from a single center. GH treatment was added (GH-plus group) in the mid-luteal phase of the previous menstrual cycle to 47 of the women who underwent controlled ovarian stimulation with the flexible antagonist protocol. 46 women, as another group, were applied to a flexible antagonist-only protocol (GH-free group). The IVF outcome results were evaluated and compared within the groups. RESULTS The number of retrieved oocytes was statistically significantly higher in the GH-plus group (2.28±1.975) than in the GH-free group (1.24±1.728) (p=0.01). Although statistically insignificant (p=0.55), the clinical pregnancy rate was higher in the GH-plus group [(8/47), 17%] than in the GH-free group [(5/46, 11%]. The cancellation rate was statistically significantly higher in the GH-free group (65.2%) than in the GH-plus group (44.7%) (p=0.04). No oocyte retrieved cycle rate was higher in the GH-free group (56%) than in the GH-plus group (25%) (p=0.002). CONCLUSIONS Adjuvant GH therapy administration to IVF protocol in the mid-luteal phase gives poor ovarian response or non-responder women a chance to have a baby.

Abstract
Aims To investigate the distribution, characteristics, and association with subarachnoid hemorrhage (SAH) of aneurysms identified in Turkish adult patients with computed tomography angiography (CTA) performed with suspicion of intracranial aneurysms and/or SAH. Subjects and Methods A total of 356 patients (164 male, and 192 female) with a mean age of 55.6 ± 4.0 (range, 18-90) years were analyzed retrospectively. The dimension in millimeters, localization, type, and multiplicity of aneurysms were noted. The differences in these parameters between females and males were investigated. The correlations of sex, aneurysm size, multiplicity, and size with SAH were researched. Results On 356 CTA, 140 cases were identified to have aneurysm (39.3%) (56 males [40.0%], 84 females [60.0%]). The incidence of aneurysms and SAH in females was high relative to males. In 140 patients, a total of 187 aneurysms were present (mean size, 7.25 ± 2.56 mm). The highest number of aneurysms was found in the middle cerebral artery 64 (34.2%) while the least was in posterior circulation 20 (10.7%). There was no significant difference between genders in terms of aneurysm size, type, and multiplicity. Individuals with aneurysm site on the internal carotid artery had lower SAH incidence. Receiver Operating Characteristic curve analysis results determined that individuals with aneurysm size >13.5 mm had increased incidence of SAH. Conclusions The general properties of intracranial aneurysms investigated with CTA in Turkish adults had similarities to information defined in the literature. These results will likely be beneficial to direct approaches to aneurysm diagnosis and treatment in routine practice.

Abstract
The aim of this study was to assess the diagnostic contribution of gray-scale ultrasonography, color Doppler, superb microvascular imaging and shear wave elastography in thyroid dyshormonogenesis (TD). From October 2017 to February 2018, the prospective study included 31 patients (13.6 y; 11-14 y) diagnosed with TD based on thyroid scintigraphy and perchlorate discharge tests and 40 healthy pediatric volunteers (12.8 y; 10-16 y). Median resistive indices (RIs), peak systolic and end-diastolic velocities, vascularity indices (VIs) via superb microvascular imaging and shear wave elastography parameters were evaluated. Median VI values were significantly higher and median RI values were significantly lower in the study group than the control group. No significant difference was found between shear wave elastography parameters of the TD and control group. VI was significantly correlated with median total thyroid gland volumes (p = 0.002, r = 0.28), medication dosage (p = 0.03, r = 0.48) and 2-h radioactive iodine uptake values (p = 0.008, r = 0.57). VI is a clinically significant and novel parameter useful for diagnosing TD.

Abstract
AIMS To compare the effects of 2 and 5 min of passive static stretching (SS) on stiffness and blood flow in the rectus femoris in adolescent athletes using shear wave elastography (SWE) and superb microvascular imaging (SMI).Material and methods: This prospective study included 20 male athletes with median age of 14.5 (12.5-16.5) years. The subjects were divided into two groups based on the SS duration as follows: 2 min (n=10) and 5 min (n=10). At rest and after 2 and 5 min of SS, stiffness and blood flow values were compared in the rectus femoris for each group. Inter-operator reliability was also analysed. RESULTS There was no significant difference between resting and 2 min of SS in terms of stiffness. The stiffness values decreased significantly from resting to 5 min of SS. The blood flow increased significantly from resting to 2 and 5 min of SS. Inter-operator reliability was moderate to perfect for SWE and SMI measurements (ICC: 0.52-0.83). CONCLUSIONS SWE and SMI can be used to acquire reliable quantitative data about muscle stiffness and blood flow in adolescents. While stiffness parameters significantly decreased from resting after only 5 min, blood flow significantly increased both after 2 and 5 min. For physical rehabilitation protocols, 5 min of SS may be chosen to reduce stiffness. For competitions, 2 min of SS may be sufficient for warm-up exercise because it increases the blood flow optimally. Five min of SS may be preferred for the cool-down exercise to enhance recovery.

Abstract
Chronic granulomatous disease (CGD) is a rare primary immunodeficiency disorder identified by recurrent pyogenic and fungal infections infections secondary to defective nicotinamide adenine dinucleotide phosphate oxidase enzyme. In the present study, we demonstrated a case with a history of multiple segmental lung resections because of invasive bronchopulmonary aspergillosis, multifocal hepatic and splenic granulomas, bilateral adnexal calcific foci presumed to be related with old granulomatous infection and finally gastric outlet obstruction secondary to the involvement of the stomach wall thickening with granulomatous tissue. This is an extremely severe case of CGD with multiorgan involvement within a 10-year period after the diagnosis. Gastric antral involvement may mimic inflammatory bowel diseases in such cases, and intestinal involvement can reliably be demonstrated via ultrasonography. Spontaneous resolution of the antral involvement was observed in the follow-up.

Abstract
Background Mycoplasma hominis is often present in the amniotic cavity with microbial invasion associated with spontaneous preterm labor. Conventional culture method is the gold standard for detection of Mycoplasmas, but real-time polymerase chain reaction (real-time PCR) has revolutionized the diagnosis of M. hominis. Objective The purpose of this study is the comparison of the culture methodology with real-time PCR for the detection of M. hominis in amniotic fluid samples. Methods Amniotic fluid samples were collected from 65 pregnant women (age range: 25-45 years) previously followed at an infertility clinic. They were collected by transabdominal genetic amniocentesis during 16-21 weeks of gestation. Amniotic fluids were inoculated in SP4 broth for 48-72 h, and after becoming alkaline, culture suspension was spread on A7 agar plate for 1 week till the typical colonies seen in "fried-egg" morphology under stereomicroscope. DNA was extracted using a QIAGEN Mini DNA kit. The real-time-PCR was performed using Rotor-Gene Q Real-time PCR instrument. A melting-curve analysis was also performed. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were measured by real-time PCR by taking culture as gold standard. Results Sixty-five women in 16-21 weeks of gestation, with a mean age of 33 ± 5.06 years, were enrolled into this study. M. hominis detected by culture and real-time PCR assay was 72% (47/65) and 69% (45/65), respectively. 66% (43/65) specimens were positive by both methods. Real-time PCR sensitivity was 91.5%, specificity 88.9%, PPV 95.6%, and NPV 80%. Conclusion Rapid detection of Mycoplasmas causing maternal complications such as neonatal infections and preterm labor in pregnancy by real-time PCR may be important and necessary. The high sensitivity and shorter time requirement of real-time PCR support its further development for diagnosis of Mycoplasma infections.

Abstract
OBJECTIVES Parotid gland (PG) involvement is common among the patients with HIV infection. Shear wave elastography (SWE) is a noninvasive method used to measure the tissue stiffness of several organs including PG. The aim of this study was to evaluate the tissue stiffness values of PGs of HIV-infected children via SWE and compare the results with the counterparts of healthy subjects. MATERIALS AND METHODS This single-center, prospective study included the PG examinations of 23 pediatric HIV patients and 40 healthy children via grayscale ultrasound and SWE. Independent sample T test and Mann-Whitney U test were used in statistical analysis. RESULTS Stiffness of both PGs was significantly higher in patients' group when compared with control subjects. In addition, when the patients were separated into two groups according to the appearance of PG on grayscale ultrasound as homogeneous and heterogeneous, stiffness values were increased in the patients with homogeneous parenchymal appearance. No significant difference was achieved in terms of median CD4 and CD8 counts, HIV RNA levels or median duration of illnesses. CONCLUSIONS PG examination of HIV-infected children via SWE reveals increased tissue stiffness when compared with healthy subjects. SWE can be used as an ultrasound-assisted noninvasive technique in this manner.

AIM To evaluate the role of superb microvascular imaging along with greyscale and Doppler imaging for thyroid gland evaluation in Hashimoto's thyroiditis (HT) versus control subjects. MATERIALS AND METHODS The study included 33 healthy volunteers with normal ultrasound and laboratory findings and 70 patients with HT based on laboratory and sonographic findings who were undergoing follow-up and receiving medical treatment. HT patients were classified based on the modification of the scheme proposed by Sostre and Reyes that incorporates the extent of hypoechoic foci or patchy infiltration as grade A (foci involving <50% of the gland) and B (foci involving >50% of the gland). Thyroid volume, mean resistive indices, peak-systolic and end-diastolic velocities based on Doppler imaging, and vascularity index via superb microvascular imaging were obtained using a Canon Aplio 500 ultrasound device using a linear 10-14 MHz transducer. RESULTS Patients with HT had significantly higher median thyroid volume and peak-systolic velocities (7.32 ml and 19 cm/s, respectively) compared to control subjects (4.62 ml and 16 cm/s, respectively). HT patients had significantly higher median vascularity index (VI; 13.5%) compared to control subjects (7.95%). A significant fair positive correlation with VI and anti-thyroglobulin antibody levels (r=0.356, p<0.05) and significant moderate positive correlation with VI and anti-thyroid peroxidase antibody levels (r=0.503, p<0.05) were found. In HT diagnosis, the optimal VI cut-off value was 10.58% with a sensitivity and specificity of 67.1% and 90%, respectively. CONCLUSION Superb microvascular imaging appears to allow assessment of subtle vascularity changes in early HT stages that cannot be detected by Doppler parameters. This technique demonstrates excellent visualization of the microvascular structures and quantitative assessment based on a novel parameter such as VI.

Abstract
OBJECTIVE To determine the diagnostic utility of a vascularity index via superb microvascular imaging in lymph nodes of children with malignant lymphoma and acute lymphadenitis compared to normal lymph nodes. METHODS We performed a retrospective study for multiparametric lymph node (LN) evaluation. Malignant lymphoma diagnosed via histopathological examination and lymph nodes receiving an acute lymphadenitis diagnosis based on clinical and laboratory findings constituted the study subgroups. We calculated a shape index [SI (percent of shortest to longest diameter)] using grayscale ultrasonography and elasticity and velocity values via shear wave elastography (SWE) as well as a vascularity index (VI) using superb microvascular imaging (SMI) for comparison with normal lymph nodes. RESULTS 45 lymph nodes diagnosed with malignant lymphoma, 72 lymph nodes diagnosed with acute lymphadenitis and 146 normal lymph nodes were evaluated. For differentiating lymphoma from normal lymph nodes, vascularity index cut-off values higher than 15% represented a diagnostic accuracy of 95%; cut-off elasticity values higher than 17 kPa exhibited a diagnostic accuracy of 99%. Optimal VI, elasticity, velocity and SI cut-off values in differentiating lymphoma from lymphadenitis were 15%, 17 kPa, 2.45 m sn-1 (p < 0.001) and 65% (p < 0.002) with calculated diagnostic accuracies of 83, 87, 88 and 68%, respectively. CONCLUSION Vascularity index values obtained via superb microvascular imaging and SWE would be reasonably useful in differentiating malignant lymphoma and acute lymphadenitis from normal LNs. SWE would be more efficient in distinguishing malignant lymph nodes from acute lymphadenitis compared with superb microvascular imaging. Advances in knowledge: Vascularity index by superb microvascular imaging would be a novel Doppler parameter in differentiating both lymphoma from lymphadenitis and also lymphadenitis from normal lymph nodes.

Abstract
AIMS Athletic performance in basketball comprises the contributions of anaerobic and aerobic performance. The aim was to investigate the effects of passive muscle stiffness, using shear wave elastography (SWE), as well as muscle thickness, and body mass index (BMI), on both aerobic and anaerobic performances in adolescent female basketball players.Material and methods: Anaerobic and aerobic (VO2max) performance was assessed using the vertical jump and shuttle run tests, respectively, in 24 volunteer adolescent female basketball players. Passive muscle stiffness of the rectus femoris (RF), gastrocnemius medialis (GM), gastrocnemius lateralis (GL) and soleus muscles were measured by SWE, and the thickness of each muscle was assessed by gray scale ultrasound. The BMI of each participant was also calculated. The relationship between vertical jump and VO2max values, and those of muscle stiffness, thickness, and BMI were investigated via Pearson's correlation and multivariate linear regression analysis. RESULTS No significant correlation was observed between muscle stiffness and VO2max or vertical jump (p>0.05). There was significant negative correlation between GL thickness and VO2max (p=0.026), and soleus thickness and VO2max (p=0.046). There was also a significant negative correlation between BMI and VO2max (p=0.001). Conclusions: This preliminary work can be a reference for future research. Although our article indicates that passive muscle stiffness measured by SWE is not directly related to athletic performance, future comprehensive studies should be performed in order to illuminate the complex nature of muscles. The maintenance of lower muscle thickness and optimal BMI may be associated with better aerobic performance.

Abstract
OBJECTIVES We aim to determine parotid gland elasticity values from healthy children and adolescents using shear wave elastography (SWE). We also define the degree of vascularity using superb microvascular imaging (SMI), power Doppler (PD), and color Doppler (CD) and compare SMI with CD and PD. MATERIALS AND METHODS A total of 100 cases, comprising 50 girls and 50 boys, with ages ranging from 3 to 17 years were included in this prospective study. SWE, SMI, PD, and CD measurements were taken from both parotid glands, and the relationships with sex, age, and body mass index (BMI) were determined. The SMI was compared with the PD and CD. RESULTS The median elasticity values measured with SWE were 8.37 ± 2.09 kPa and 1.68 ± 0.26 m/s on the right and 8.33 ± 2.04 kPa and 1.69 ± 0.26 m/s on the left. There were significant positive correlations present for those aged below and above 10 years and for BMI with elasticity values. The median vascular spot numbers measured using SMI, PD, and CD were 5 ± 1.70, 3.5 ± 1.45, and 2 ± 1.1 on the right and 4 ± 1.7, 4 ± 1.43, and 2 ± 1.05 on the left, respectively. The median values obtained with SMI were significantly higher than the median values obtained with both PD and CD. CONCLUSION This study determined the reference SWE, SMI, PD, and CD values for normal parotid glands in healthy children and adolescents. Elasticity values were affected by age and BMI. There was no correlation between vascularity values and age, sex, or BMI. SMI provided more detailed information about vascularity compared with the other methods.

Abstract
BACKGROUND Understanding the coeliac trunk (CeT) and hepatic artery anatomy is important not only in preventing iatrogenic injuries but also in planning surgical procedures in children. Therefore, the aim of this study is to analyse the prevalence of CeT and common hepatic artery (CHA) variations in the paediatric population. MATERIALS AND METHODS One hundred and seventy-four children who underwent abdominal multidetector computed tomography (MDCT) angiography, either because of trauma or liver transplantation, were analysed retrospectively. The patterns of CeT, CHA and their variant branches were revealed and compared with previous studies involving adults. RESULTS A total of 157 (90.2%) of the 174 patients had normal CeT anatomy, whereas 17 (9.8%) had variations. Five types of CeT variations were identified according to Song's classification in which 'hepatosplenic trunk + left gastric artery + superior mesenteric artery' was the most prevalent. One hundred-twelve (64.4%) of the 174 patients had normal CHA anatomy; however, 62 (35.6%) had variations. Six types of CHA variations were identified according to Michel's and Hiatt's classification. The most common was 'replaced left hepatic artery originating from left gastric artery'. CONCLUSIONS The prevalences of CeT and hepatic artery variations are high in children, as they are in older patients. Awareness of these variations is important in terms of avoiding iatrogenic injury and in promoting surgical procedure planning for liver transplantation or abdominal tumour surgery.

Abstract
BACKGROUND Microalgae are uniquely advantageous organisms cultured and harvested for several value-added biochemicals. A majority of these compounds are lipid-based, such as triacylglycerols (TAGs), which can be used for biofuel production, and their accumulation is most affected under nutrient stress conditions. As such, the balance between cellular homeostasis and lipid metabolism becomes more intricate to achieve efficiency in bioproduct synthesis. Lipidomics studies in microalgae are of great importance as biochemical diversity also plays a major role in lipid regulation among oleaginous species. METHODS The aim of this study was to analyze time-series changes in lipid families produced by microalga under different nutrient conditions and growth phases to gain comprehensive information at the cellular level. For this purpose, we worked with a highly adaptable, oleaginous, non-model green microalga species, Ettlia oleoabundans (a.k.a. Neochloris oleoabundans). Using a mass spectrometry-based untargeted and targeted metabolomics' approach, we analyzed the changes in major lipid families under both replete and deplete nitrogen and phosphorus conditions at four different time points covering exponential and stationary growth phases. RESULTS Comprehensive analysis of the lipid metabolism highlighted the accumulation of TAGs, which can be utilized for the production of biodiesel via transesterification, and depletion of chlorophylls and certain structural lipids required for photosynthesis, under nutrient deprived conditions. We also found a correlation between the depletion of digalactosyldiacylglycerols (DGDGs) and sulfoquinovosyldiacylglycerols (SQDGs) under nutrient deprivation. CONCLUSIONS High accumulation of TAGs under nutrient limitation as well as a depletion of other lipids of interest such as phosphatidylglycerols (PGs), DGDGs, SQDGs, and chlorophylls seem to be interconnected and related to the microalgal photosynthetic efficiency. Overall, our results provided key biochemical information on the lipid regulation and physiology of a non-model green microalga, along with optimization potential for biodiesel and other value-added product synthesis.

Abstract
Purpose: To evaluate the contribution of conventional brain magnetic resonance imaging (MRI) for the determination of intracranial aneurysms. Materials and Methods: Brain MRI and computed tomography angiography (CTA) of 45 patients (29 women and 16 men; age range, 32–80 years) with aneurysm were analyzed. A comparison was made between brain MRI and CTA based on size and presence of aneurysm. The comparisons between MRI and CTA were investigated through Bland-Altman graphics, receiver operating characteristic curve, and Kappa statistics. Results: Fifty-seven aneurysms were evaluated. Forty-five percent of 57 aneurysms on CTA were detected on conventional brain MRI. A significant correlation was found between CTA and brain MRI in the diagnosis of aneurysm (P < 0.05). In an analysis of the size measurement, a significant correlation was observed between CTA and brain MRI. Seventy-seven percent of aneurysms <4 mm was not detected and the efficiency of MRI in the detection of aneurysms <4 mm was found to be low. Conclusion: Aneurysms can also be appreciated on conventional brain MRI, and vascular structures should be reviewed carefully while analyzing brain MRI.

Abstract
OBJECTIVE To investigate whether amnioreduction has any impact on emergency cervical cerclage outcome. MATERIALS AND METHODS Data of women who underwent emergency cervical cerclage for advanced cervical dilatation and protruding membranes were analyzed retrospectively. RESULTS During the study interval, a total of 56 women who were underwent amnioreduction (n=26) and who did not (n=30) were eligible for analysis of the study. Gestational age at cerclage, delivery, and prolongation of pregnancy interval were comparable between the groups (21.3 ±3.3 vs. 20.6 ±3.1 weeks; p = 0.44; 28.3 ±6.1 vs. 28.1 ±5.6 weeks; p = 0.74; 53.7± 46.1 vs. 47.3± 36.7 days; p = 0.56 respectively). Number of live birth rates and perinatal mortality rates were also not statistically significantly different between the groups (73.1% vs. 70.0%; p = 0.80; 15.4% vs. 13.3%; p = 0.83). CONCLUSIONS Emergency cerclage yields live take home baby rates in more than half of the patients. The decision to perform amnioreduction should be based on suspicion of chorioamnionitis and patient's motivation to know exactly what is the risk of chorioamnionitis.

Abstract
In patients with high-grade atherosclerotic stenosis or occlusion of the extracranial cerebral arteries, subarachnoid hemorrhage (SAH) may occur, potentially due to rupture of fragile dilated pial collateral vessels. This association has been well described in Moyamoya disease. There are only few cases in the literature that reported SAH due to bilateral carotid artery stenosis but intraventricular hemorrhage caused by dilated pial collateral has not been reported yet. We present a case of bilateral carotid artery occlusion presented with intraventricular hemorrhage. Based on the findings in the present case, carotid artery stenosis or occlusion may present with intraventricular hemorrhage due to rupture of the dilated, fragile collateral vessels.

Abstract
OBJECTIVE To evaluate whether symptoms and recurrence would differ with and without Cu-IUD removal in patients with concomitant biofilm forming Candida spp. METHODS The data of 270 consecutive patients wearing TCu380A Cu-IUD were evaluated. Among these patients, 100/270 were found to have Candida spp. isolated from the tail of Cu-IUD or vaginal samples. These patients were investigated in four groups: Group 1 (n = 24; Biofilm (+), Cu-IUD removed), Group 2 (n = 14; Biofilm (+), Cu-IUD not removed), Group 3 (n = 29; Biofilm (-), Cu-IUD removed), Group 4 (n = 33; Biofilm (-), Cu-IUD not removed). Patients in each group were followed for clinical signs and symptoms for 8-16 months and compared to each other. RESULTS Symptoms, physical findings and candida positivity have decreased statistically significantly in Group 1 one year after removal of Cu-IUD (95.8% vs. 4.2%, p < 0.01; 95.8% vs. 4.2%, p < 0.01; 100% vs. 8.3%, p < 0.01 respectively). In Group 2, symptoms, physical findings and candida positivity have decreased after follow-up, but without a statistical significance. In Group 3, all the parameters have decreased, but only decrease in candida positivity has reached statistical significance (100% vs. 48.3%, p < 0.01). In Group 4 - as in Group 1- symptoms, physical findings and candida positivity have decreased statistically significantly (48.5% vs. 18.2%, p = 0.01; 72.7% vs. 48.5%, p = 0.05; 100% vs. 51.5%, p < 0.01 respectively). CONCLUSION Biofilm forming microorganisms should be considered in the management of vaginal infections or symptoms for safer use of intrauterine devices.

Abstract
We investigated bovine coronavirus (BCoV) as an etiological agent in cattle with clinical respiratory and digestive signs using 147 feces and 199 nasal swab samples. A total of 18 test samples (16 feces and 2 nasal swap samples) were detected positive by ELISA and/or RT-PCR targeting the BCoV N gene. The partial S1 gene regions of BCoVs (An-4 and An-11) detected in feces samples from two herd-mate dairy calves were compared. Virological and serological results indicated that BCoVs are widespread in Turkey and are likely etiological agents in diarrhea cases in calves.

Abstract
BACKGROUND We investigated the effect of thoracic epidural anesthesia on perioperative blood glucose levels in diabetic patients undergoing cardiopulmonary bypass by continuous insulin infusion according to the Portland Protocol. MATERIAL AND METHODS Diabetic patients undergoing surgery with cardiopulmonary bypass were assigned to receive either general anesthesia alone (n=40) or general anesthesia with thoracic epidural anesthesia (n=18). Patient data were retrospectively reviewed from prospective chart records used in our anesthesia clinic. In all study patients, insulin infusion with the Portland Protocol was used to maintain stable blood glucose levels. We evaluated blood glucose levels in both groups at 6 time points including before surgery, before cardiopulmonary bypass, during cardiopulmonary bypass, immediately following cardiopulmonary bypass, and on the first and second postoperative days. The amounts of insulin required at the intraoperative period and during two postoperative days were compared between two groups. RESULTS Groups were similar with respect to the duration of cardiopulmonary bypass, aortic cross-clamping, surgery, and blood glucose levels at any of the 6 time points, mean insulin requirements during intraoperative period and mean insulin requirements and blood glucose levels during the first 2 postoperative days (General anesthesia alone, 189+/-29 mg/dl vs. General anesthesia with thoracic epidural anesthesia, 191+/-19 mg/dl; p=0.782). CONCLUSIONS In diabetic patients undergoing cardiopulmonary bypass receiving insulin infusion by the Portland Protocol for glycemic control, thoracic epidural anesthesia provides no additional benefit for maintaining blood glucose levels during surgery.

Abstract
OBJECTIVES To determine the efficacy of an application regimen of low-dose frequent misoprostol for second-trimester pregnancy termination. METHODS A total of 250 women between 12 and 20 weeks of gestation who were scheduled for second-trimester pregnancy termination received 200 microg vaginal misoprostol followed by 100 microg oral misoprostol every 2 h until expulsion of the fetus. Mechanical cervical dilatation with a 16-French Foley balloon catheter was performed if no cervical dilatation was observed after 24 h. The main outcome measures were the delivery rate within 24 h and the factors influencing the interval between the onset of induction and abortion. Secondary outcome measures were the side-effects of the regimen and the total misoprostol dose required. RESULTS With application of this protocol, 245 women (98%) delivered within 24 h of induction. The mean (+/-standard deviation) misoprostol dose used was 728+/-297 microg (200-2100 microg). Cox regression analysis revealed that vaginal spotting or nulliparity do not effect the induction-abortion time. On the other hand, using this regimen induction to abortion time tends to be longer in the presence of live fetuses (odds ratio (OR) = 0.45; confidence interval (CI) =0.2-0.8; p=0.008) and pregnancies with gestational age > 16 weeks (OR= 0.59; CI = 0.4-0.8; p= 0.003) when compared with cases of in utero death and pregnancies with a gestational age of 12-13 weeks, respectively. Twenty-seven women (10.8%) experienced one or more side-effects attributable to misoprostol. CONCLUSION The 100-microg oral misoprostol every 2 h following 200 microg vaginal misoprostol is a highly effective protocol for inducing abortion at 12-20 weeks of pregnancy. Cases with live fetuses or pregnancies with older gestational age (> 16 weeks) deliver in a longer time period.

Abstract
OBJECTIVE To compare the effectiveness of sublingual and vaginal misoprostol application for cervical ripening prior to manual vacuum aspiration (MVA) under local anaesthesia for voluntary termination of pregnancy between 7 and 10 weeks of gestation. MATERIALS AND METHODS Prospective randomized study in which 72 women were randomly assigned to administration of either 400 microg vaginal misoprostol 3 hours prior to or 200 microg sublingual misoprostol 2 hours prior to the surgical procedure. We took the preoperative cervical dilatation that was achieved as the main outcome measure. The duration of the procedure, intra-operative blood loss, pain perception before and during the operation, patients' satisfaction, side effects and duration of post-operative bleeding were secondary outcome measures. RESULTS A similar pre-operative cervical dilatation was achieved in the sublingual and the vaginal groups (6.9 +/- 1.6 mm and 6.6 +/- 1.1 mm, respectively; p = 0.3). The duration of the operation, intra-operative blood loss, and patients' satisfaction did not differ between the two groups. Pain scores were significantly higher in the sublingual group than in the vaginal group, both after administration of misoprostol (p = 0.02) and during the procedure (p = 0.02). Nausea and vaginal spotting were significantly more frequent (p = 0.01 and p = 0.003, respectively), but post-operative bleeding significantly shorter (p = 0.003) in the sublingual group. CONCLUSION Administration of 200 microg sublingual misoprostol 2 hours before suction curettage under local anaesthesia was as effective as 400 microg vaginal misoprostol 3 hours before that procedure with regard to achieving cervical dilatation. It resulted in higher pre-operative and intra-operative pain scores without changing patients' satisfaction.

Abstract
PURPOSE To integrate cervical length measurement into antenatal screening and apply emergency cerclage when indicated to prevent spontaneous deliveries at < 34 weeks of gestation. METHODS Cervical length measurements of 400 pregnant volunteers were obtained at gestational weeks 12-14, 18-20 and 28-32. Whenever a cervical measurement < 30 mm was observed, vaginal cultures and bacterial vaginosis were investigated, and weekly cervical length measurements were performed thereafter. Emergency cerclage was performed whenever complete cervical effacement and > or = 3 cm cervical dilatation were observed before 32 completed weeks of gestation. We adopted and tested a strategy of only emergency cerclage application when clinically indicated after ultrasound screening and microbial monitoring of short cervices. Patients were given cyclooxygenase-inhibitors, progesterone, and antibiotics in the postoperative period. RESULTS Spontaneous preterm births at < 34 weeks of gestation occurred in 15 women (3.8%). We performed five emergency cerclages according to the presented screening strategy between 20-28 weeks of gestation all of which reached > 34 weeks. We successfully postponed 62.5% (5/8) of deliveries before 32 completed weeks and 33.3% (5/15) of deliveries before 34 completed weeks. CONCLUSION Routine cervical length measurement combined with serial transvaginal sonograms and vaginal microbial monitoring of the short cervices will avoid unnecessary prophylactic cerclages while increasing the success of emergency cerclages performed upon solid clinical findings.

Abstract
BACKGROUND AND OBJECTIVE We have evaluated the effects of propofol and its relationship with K+ channels on human isolated umbilical vessels. METHODS Umbilical vessel rings were suspended in isolated organ baths containing Krebs-Ringer solution. In the first series of experiments the effect of propofol (10(-9)-10(-4) M) was examined in a concentration-dependent manner on umbilical vessels precontracted with KCl (60 mmol). In the second series, these effects were studied in the presence of tetraethylammonium. RESULTS A mild contraction was produced by low dose propofol in both precontracted umbilical artery and umbilical vein segments. 10(-4) M propofol caused significant relaxation in both umbilical artery and umbilical vein. The relaxation response was significantly reduced by the addition of 10(-1) M tetraethylammonium. CONCLUSION These results suggested that the responses of propofol on KCl-induced contractions of both umbilical artery and vein were dose dependent, and this effect involved Ca2+ activated K+ channels.

Abstract
OBJECTIVE To compare the obstetric outcome of induction of labor at 41 weeks and of follow-up until 42 weeks and induction if the patient has still not given birth at 42 weeks. STUDY DESIGN Six hundred women at 287+/-1 days of gestation with definitely unfavorable cervical scores were randomized to labor induction (N=300) or spontaneous follow-up (N=300) with twice-weekly nonstress testing and amniotic fluid measurement and once-weekly biophysical scoring. The treatments used in the induction group were (1) vaginal administration of 50 microg misoprostol (n=100), (2) oxytocin induction (n=100), and (3) transcervical insertion of a Foley balloon (n=100). The primary outcome measures were the cesarean delivery rate, whether or not the normal hospital stay had to be extended, and the neonatal outcomes. Secondary outcome measure included number of emergency cesarean deliveries performed for abnormalities of the fetal heart rate (FHR). RESULTS The abdominal delivery rate was 19.3% in the induction group and 22% in the follow-up group (p=0.4). The mean length of hospital stay in the two main groups was 1.4+/-0.8 days and 1.3+/-1 days, respectively (p=0.1). Significantly higher rates of macrosomia and shoulder dystocia were seen in the follow-up group (24.6 and 2.3%) than in the induction group (7.6%, p<0.001; 0.3%, p=0.03). Meconium-stained amniotic fluid and meconium aspiration syndrome were observed significantly less frequently in the induction group (9.3 and 1.3%) than in the follow-up group (20.3%, p<0.001; 4%, p=0.03). Rates of emergency abdominal delivery in response to worrying FHR traces, neonatal intensive care unit admission, and low umblical artery pH were similar in the two groups. There was one intrauterine fetal death in the follow-up group. CONCLUSION Induction of labor at 41 weeks of gestation does not increase the cesarean delivery rate or cause a longer stay in hospital than follow-up until 42 weeks, and neonatal morbidity is also lower after induction.

Abstract
We aimed to evaluate the effects of ovulation induction on Ki67 expression and dysplasia scores of female rat ovaries. Twenty female Wistar rats were randomized either to receive 150 IU/kg human menopausal gonadotropin on estrous day 2 and 75 IU/kg human chorionic gonadotropin on the day of preestrous (induction group, n= 10) or saline as placebo on the corresponding days (control group, n= 10). After five estrous cycles bilateral oophorectomy was performed to compare the Ki67 expression and dysplasia score of the ovarian epithelium. The mean number of the cells that stained positive for Ki67 was 159.6 +/- 101.92 in the follicles, 283.4 +/- 42 in the corpus luteum, and 151 +/- 75.1 in the stroma of the study group compared to 41.8 +/- 35.6 (P= 0.03), 43.2 +/- 28.3 (P= 0.007), and 55.6 +/- 18.6 (P= 0.01), respectively, in the control group. The mean number and rate of cells that stained positive for Ki67 in the epithelium was significantly higher in the ovulation induction group (758 +/- 71 and 63 +/- 1.6%, respectively) compared to the control group (386 +/- 23, P < 0.001; and 60 +/- 1.1%, P < 0.001; respectively). The mean dysplasia score was significantly higher (9.6 +/- 1.3) in the study group compared to the control group (5.08 +/- 0.9, P < 0.001). Ovulation induction in rats resulted in increased Ki67 expression and dysplastic features in the ovarian epithelial cells.

Abstract
BACKGROUND AND OBJECTIVES To compare the analgesic effects of intrathecal fentanyl and low-dose intravenous ketamine as adjuvants to intrathecal bupivacaine for Caesarean section. METHODS Ninety elective Caesarean section patients were randomized into three groups. Spinal anaesthesia was performed with 15 mg hyperbaric bupivacaine in all groups. Ketamine (0.15 mg kg(-1)) or an equal volume of normal saline was given intravenously immediately after initiating spinal anaesthesia in the ketamine and control group, respectively. In the fentanyl group, 10 microg fentanyl was added to the intrathecal bupivacaine. Arterial pressures, heart rate values, adverse effects, the time of first request for postoperative analgesia, visual analogue pain scores, total analgesic consumptions at 24 and 48 h were recorded in all patients. RESULTS The time to first request for analgesia was significantly longer in the ketamine (197 min) and fentanyl (165 min) groups compared to the control group (144 min). Postoperative pain scores were significantly lower in the ketamine group than in both other groups. Although the analgesic requirements during first 24 h were significantly lower in the ketamine group, there was no significant difference between the groups during the following 24 h. CONCLUSION Intravenous low-dose ketamine combined with intrathecal bupivacaine for Caesarean section provides longer postoperative analgesia and lower postoperative analgesic consumption than bupivacaine alone suggesting a pre-emptive effect.

Abstract
AIM To find out the predictors of ICSI outcome. METHODS Forty-three pregnancies in 100 consecutive ICSI cycles. RESULTS Every 1,000 pg/ml increase in hCG-day E2 (OR = 0.46, CI: 0.25-0.83, p = 0.01) and 1% decrease in the rate of normal sperm morphology (OR = 0.81, CI: 0.67-0.98, p = 0.03) caused a significant decrease in clinical pregnancy rate and live birth rate (respectively, OR = 0.5, CI: 0.32-0.96, p = 0.03, OR = 0.66, CI: 0.5-0.86, p = 0.002) while every increase in the number of good quality embryos transferred caused a two-time increase in the clinical pregnancy rate (OR = 2.1, CI: 1.2-4, p = 0.01). On the other hand, every increase in the number of four-cell cleavage embryos (OR = 1.02, CI: 1.002-1.04, p = 0.03) and hCG-day endometrial thickness (OR = 1.6, CI: 1.15-2.24, p = 0.005) were found to increase the live birth rate. Implantation rate (m = 8.3 +/- 14.6) was significantly lower in cases with leucocytospermia (n = 33) compared to cases without leucocytospermia (n = 67, m = 17.4 +/- 24.6, p = 0.02). CONCLUSION Leucocytospermia, hCG-day E2 level and endometrial thickness, normal sperm morphology, and number of good quality embryos are predictors of implantation, clinical pregnancy and live birth rate following ICSI.

Abstract
Magnetic resonance (MR) imaging and MR angiography were used for the differential diagnosis and preoperative planning of a 17 weeks of age rudimentary horn pregnancy. A 26-year-old primigravida was referred to our hospital with a preliminary diagnosis of abdominal pregnancy. After an inconclusive ultrasound evaluation we were able to identify a rudimentary horn pregnancy, extent of the placental invasion, and the vascular supply via MR imaging and time of flight sequence MR angiography. The obtained data were also used for preoperative planning, which resulted in an uncomplicated, prerupture laparotomy for pregnancy termination and a healthy female.
